According to the Microsoft Research project page, the work-in-progress TouchStudio aims to bring 'the excitement of the first programmable personal computers to the phone.' Among the code examples provided is a four-liner that scans a phone's music collection for songs less than three minutes long and produces a fairly slick, clickable playlist complete with track info and artwork. Easier than iPhone SDK programming, no?
